Huawei B311 Home Router
Important. This router has been sold by Huawei since at least 2021. Unless a major feature, impacting the security of the router, is deployed on the router post CRA-enactment, it will not be required to comply with the CRA.
This Fast Check is for information purpose only.
I46’s analysis finds that this router is poorly secured and fails to meet all the requirements of the Cyber Resilience Act. Indeed, during the analysis of the router, i46 found that three core requirements of the CRA were not met:
Annex I, paragraph (b): “be made available on the market with a secure by default configuration, unless otherwise agreed between manufacturer and business user in relation to a tailor made product with digital elements, including the possibility to reset the product to its original state”;
Annex I, paragraph (d): “ensure protection from unauthorised access by appropriate control mechanisms, including but not limited to authentication, identity or access management systems, and report on possible unauthorised access;”
Annex I, paragraph (j): “be designed, developed and produced to limit attack surfaces, including external interfaces;”
Below, i46 details a few core features of the router, and provides their compliance findings for each of them.

Compliance Table
Feature | Findings | Compliance with the CRA |
---|---|---|
Unique Password | No: the password is admin | 🔴 No |
Strong password enforcement | No | 🔴 No |
Minimal surface (physical) | The device includes RJ-45 ports, power and reset ports | 🟢 Yes |
Minimal surface (software) | Port 80 (http) is open | 🟢 Yes: this port is required for device management. |
Minimal surface (software) | Port 53 (domain) is open | 🔴 No: DNS server should be optional as, in many cases, this feature is not used. (Severity: Low) |
Minimal surface (software) | Port 20249 (Link quality information) is open | 🔴 No: It is not clear why this information is required for the end-user. Technical information port should be closed by default. (Severity: High) |
Minimal surface (software) | Port 31215 (UPnP as http) is open | 🔴 No: UPnP service should be optional and closed by default. CVE-2017-17215 is associated with port 37215. This could potentially allow attackers to take control of the device. (Severity: Very High) |
Minimal surface (software) | Port 37443 (UPnP as https) is open | 🔴 No: UPnP service should be optional and closed by default. (Severity: Medium) |
As shown in the above table, the Huawei B311 fails i46’s Fast Check.
While the device does not need to comply with the Cyber Resilience Act, due to being manufactured before the Act’s enactment, it bears highlighting that the weaknesses identified during the Fast Check means that businesses and people wishing to use this router should proceed with caution.

ACHIEVING COMPLIANCE
I am an IoT device manufacturer
IoT device manufacturers are first in line when it comes to compliance.
The CRA will change the way manufacturers operate.
Our guide covers what you have to do, how much time you have to comply and what the legal ramifications of non-compliance are.
I am a software developer
While free and open-source software, providing that their makers do not derive any profit from their distribution, does not fall under the purview of the Cyber Resilience Act, non-embedded software and software that remote process data from IoT devices need to comply with the Act.
I import / distribute/ resell
IoT device importers, distributors and resellers have many requirements under the CRA and in some circumstances can even be considered as manufacturers themselves.
Our guides detail these stakeholders’ responsibilities and liabilities.
